When the phenotype (trait) is a mixture of what the different alleles code for, it is known as incomplete dominance.
For example:
- if B codes for black fur, and b codes for white fur - incomplete dominance would result in grey fur (a mix of black and white) for a rabbit with Bb alleles.
- if R codes for red flowers, and r codes for white flowers - incomplete dominance would result in pink flowers for a plant with Rr alleles.

When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What happens when different alleles of the trait are present?
When different alleles of a trait are present, one allele may be dominant over the other, expressing its associated trait while the recessive allele remains hidden. In some cases, both alleles may exert influence, resulting in a blending or co-dominant expression. Additionally, the presence of multiple alleles can lead to a range of phenotypic variations within a population.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
What is the key recognition of codominance?
The heterozygote expresses the phenotype of both homozygotes.
In some flowers there are two alleles for color and these can both be expressed equally at the same time Which best describes this trait?
This trait is known as co-dominance, where two alleles for a particular gene are both fully expressed in the phenotype. In this case, both colors are visibly present in the flower, rather than blending to create a new color.
What is a trait that is not expressed from a living thing thing that has received genes for two different forms of that trait?
Incomplete dominance is a trait that can result when an organism receives genes for two different forms of the same trait. In this case, neither form of the trait is fully expressed, leading to a blending of the two forms.
When one trait is not completely dominant over another is called a what?
When one trait is not completely dominate over another, this is called incomplete dominance. What will be seen (phenotype) will be a blending of the two.
What trait of society can prevent culture blending?
A strong emphasis on cultural isolation or preservation can prevent culture blending in society. This can be seen in societies that prioritize maintaining traditional beliefs, practices, and customs without incorporating outside influences. Additionally, strict adherence to social norms and resistance to change can also hinder culture blending.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When two alleles for a trait are different?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
Explain how Mendel's particulate hypothesis is different from the blending hypothesis of inheritance?
Mendel showed in his experiments that inherited traits are not passed through the blending of inheritance theory. According to the blending of inheritance theory, an offspring's traits are a blend between the traits of the parent organisms. In Mendel's experiments however, he showed that this was not true, and that inheritance is actually based on genes, through the observation of recessive traits. He observed that an offspring could have a trait that neither of the parents had, which is now explained through both of the parents having the recessive gene for the trait, but not showing it because they are heterozygous dominant. There is a 25% chance that the offspring of two heterozygous dominant parents will produce a homozygous recessive offspring that will show the trait that neither of the parents shows.

What does co-dominance mean in genetics?
Co-dominance is a genetic concept where both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays traits from both alleles equally. This is different from incomplete dominance, where the traits blend together. An example of co-dominance is the AB blood group system in humans.
